Pinolite,

also pinolite-magnesite, a rarely occurring rock that consists of magnesite-dolomite and graphite, and is formed only under special conditions inside the Earth's crust. Pinolite is found in high quality in the Hohentauern in Austria. It is reminiscent of edelweiss due to its flower-like grain, which is why it is also known under the trade name "edelweiss magnesite", but also under "ice flower magnesite".
